 Ridgeline Wind: Calm
 Blowing Snow: Prev Snow Available for Transport: None
 Comments: A few high clouds today. Light breeze on summit.
AVALANCHE OBSERVATIONS
 No. Location Date Size Type Trigger Aspect Elevation Comments
 Numeroius Boulders 1 WL N Many small wet loose slides on southern half of compass with a few pushing D1.5. A few in the Smokys too.
 Comments: Did not see any other non wet loose avalanches when glassing the surrounding terrain.
SNOWPACK OBSERVATIONS
 HS: n/o 
 Upper Pack: Up to 8" of dense snow sitting in south bowl just off the top. Was getting warm with some nice rollerballs but ski cuts were ineffective at 14:30. Punchy wind board or soft sastrugi in west bowl with some decent corn skiing below 8800 on S. Breakable crust from overnight freeze on top of recent storm snow in ascent trees.

Loose Wet

Layer/Depth:
10-20cm

Likelihood of Triggering
Sensitivity:
Stubborn

Spatial Distribution:
Specific
Terrain
  Primary Concern Comments: Might have been a bit early to get things moving.
 
Avalanche Characteristics
Character/Avalanche Problem:
Wind Slab

Layer/Depth:
3/29

Likelihood of Triggering
Sensitivity:
Not Observed

Spatial Distribution:
Isolated
Terrain
  Problem 2 Comments: Im sure they are lurking in a few isolated areas in the alpine but we did not encounter any on decent. Mostly just some breakable windboard in W bowl. Like in the soldiers, I saw no natural activity from last storm.

 Stability Test Results:
SNOW STABILITY
 Snow Stability Rating for your observed area: Confidence: Trend:
 Comments (aspects and elevations of instability, etc): MOD for loose wet potential and some isolated wind slabs. LOW at low elevations.
